Jon Mee has devoted his life to the study of enthusiasm. Twelve years ago, he rocketed onto the Romantic scene with his first book, Dangerous Enthusiasm, which turned out to be one of the best Blake books of the decade. A series of articles on Coleridge and other visionary writers continued to fan the flames of his following, and now he has satisfied us with Romanticism, Enthusiasm, and Regulation. . . . Mee's book is an important contribution to understanding emotion in the 18th century.
